具体实施方式
以下结合说明书附图及具体实施例进一步说明本发明的技术方案。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明实施例提供的空调设备控制方法及装置,可以应用在现有的空调设备上,以使其实现智能调节及节能环保的目的,应用范围广泛,具有较大的市场前景。
实施例 1
图 1 展示了本发明的空调设备控制方法的整个完整逻辑的具体流程,其中, T1 为室内目标温度, T2
为室内温度, T3 为室外温度,下面针对上述控制方法进行相关介绍。在本发明的一个实施例中,提供了一种空调设备控制方法,参见图 2
所示,所述空调设备控制方法包括以下步骤:
S1 、获取室内目标温度、室内温度和室外温度。
设定室内目标温度为 T1 ,室内温度为 T2 ,室外温度为 T3 ,具体地,所述室内目标温度 T1
为用户设定的目标温度,而室内温度 T2 和室外温度 T3
是通过温度传感器检测得到的,所述温度传感器可以是空调本体自带的第一温度传感器和第二温度传感器,分别检测室内和室外的温度,也可以是独立于空调设备的温度传感器,并与空调设备的控制器连接通讯,本发明对获取
T2 和 T3
的传感器的设置方式不作具体限定。本实施例提供的控制方法的最终目的是控制调节新风模式、制热模式或制冷模式,使室内温度达到设定的目标温度,即室内目标温度。
S2 、比较室内温度和室内目标温度的高低,得到温度比较结果。
参见图 1 可知,得到的温度比较结果可以分为三种,分别是 T1>T2 , T1<T2 及
T1=T2 。
S3 、识别当前模式,得到识别结果。
本申请中,空调设备具有模式识别功能,具体实现方式为:设置模式标记,通过读取所述模式标记即可实现模式识别,所述识别结果即为当前最新标记的模式状态。
S4 、根据温度比较结果和识别结果,对当前模式进行更新标记。
具体地,根据不同的温度比较结果和不同的识别结果,进行不同的标记更新,参见图 3
,列出了标记第一模式和标记第二模式两种不同的状态。
S5 、进一步根据室内温度和室外温度的比较结果,控制进入新风模式、制热模式或制冷模式。
同上,图 3 列出了进入新风模式、制热模式或制冷模式的几种不同的控制过程。
本发明的一个实施例中,所述温度比较结果包括第一比较结果和第二比较结果,下面分别对应于第一比较结果和第二比较结果,针对上述步骤 S5 进行说明:
参见图 4 ,对应于第一比较结果的控制方法包括以下流程:
S211 、温度比较结果为第一比较结果,所述第一比较结果为室内目标温度高于室内温度;
S212 、识别当前模式是否为第一模式,若否,则执行 S213 ;
S213 、标记当前模式为第二模式;
S214 、根据室内温度和室外温度的比较结果,控制进入新风模式或制热模式。
参见图 1 可知,步骤 S212
中,若判断结果为是,进一步判断室内目标温度与室内温度的差值是否超过第一超调幅值,若是,则执行第二模式动作,以实现第一模式向第二模式的转换,否则退出制冷模式和
/ 或新风模式,并等待返回 S1 进入下一轮的控制。
其中,所述进一步判断是为了在识别标记模式时识别第一模式的标记真伪,比如在秋季,利用比较室内目标温度与室内温度的差值是否超过第一超调幅值,若温差超过第一超调幅值,则判定当前的第一模式的标记为伪标记,则自动转换为第二模式,否则退出制冷模式和
/ 或新风模式。
需要说明的是,步骤 S213 和 S214 没有先后之分,本实施例中是先执行步骤 S213 ,后执行步骤
S214 ,但是明显可以看出,先执行步骤 S214 ,后执行 S213 同样可以实现本发明的技术方案,步骤 S213 和 214 组成第二模式动作。
这里,步骤 S214 为核心步骤,具体可分解为图 6 中的方法流程,包括:
S2141 、比较室内温度和室外温度的高低;
S2142 、若室内温度低于室外温度,则执行 S2143 ,否则执行 S2144 ;
S2143 、进入新风模式;
S2144 、进入制热模式。
上述步骤 S2142
中的执行条件限定于室内温度低于室外温度,则进入新风模式,否则进入制热模式,除此,也可以将执行条件放宽至一定的范围,即判定室内温度与室外温度的温度差是否超出预设的范围,若是,则进入制热模式,否则进入新风模式。采用此执行条件判断控制进入新风模式或制热模式的技术方案,同样落入本发明的保护范围。
上述步骤 S2143 具体为通入新风,由于 T1>T2 , T3>T2
,因此,通过比室内温度高的室外新风,有利于将 T2 调节为目标室内温度,充分利用了室外高温的能源,达到节能效果。
上述步骤 S2144
具体为利用空调设备中的制热组件对空气进行加热,所述制热组件包括设置在空气换热管路处的电加热器,所述电加热器工作能够将空气换热管路内的空气加热升温,由于
T1>T2>T3 ,因此,室外新风无法帮助室内提升温度,在这种情况下,需要依靠空调设备的制热组件将 T2
调节为目标室内温度。需要作出说明的是,除了制热组件实现对空气的加热,也可以利用蒸发器对空气进行加热,蒸发器加热的过程及原理与蒸发器制冷的过程及原理相同,本发明不限定具体的加热方式,其他现有技术中的空调加热方式均落入本申请的保护范围。
以上为新风模式和制热模式二者选一的方法流程,即在新风模式下,首先利用新风对室内温度作提升,然后等待返回到步骤 S1
进行温度获取,进入下一轮的控制,而在本发明的另一个实施例中,提供了一种进入新风模式后的扩展方法,参见图 10 ,流程包括:
S2143 、进入新风模式;
S2145 、判断室内目标温度是否高于室外温度,若是,则执行 S2146 ;
S2146
、同时进入制热模式,具体为,一方面,通过室外高温新风空气,另一方面,驱动空调的制热组件工作。
参见图 1 可知,步骤 S2145 中,若判断结果为否,则等待返回步骤 S1 进入下一轮的控制。
这种控制方法可以在节能控温的同时,可快速使室内温度达到目标温度。
参见图 5 ,对应于第二比较结果的控制方法包括以下流程:
S221 、温度比较结果为第二比较结果,所述第二比较结果为室内目标温度低于室内温度;
S222 、识别当前模式是否为第二模式,若否,则执行 S223 ;
S223 、标记当前模式为第一模式;
S224 、根据室内温度和室外温度的比较结果,控制进入新风模式或制冷模式。
参见图 1 可知,步骤 S222
中,若判断结果为是,进一步判断室内温度与室内目标温度的差值是否超过第二超调幅值,若是,则执行第一模式动作,以实现第二模式向第一模式的转换,否则退出制热模式和
/ 或新风模式,并等待返回 S1 进入下一轮的控制。
其中,所述进一步判断是为了在识别标记模式时识别第二模式的标记真伪,比如在春末夏初,利用比较室内温度与室内目标温度的差值是否超过第二超调幅值,若温差超过第二超调幅值,则判定当前的第二模式的标记为伪标记,则自动转换为第一模式,否则退出制热模式和
/ 或新风模式。
需要说明的是,步骤 S223 和 S224 没有先后之分,本实施例中是先执行步骤 S223 ,后执行步骤
S224 ,但是明显可以看出,先执行步骤 S224 ,后执行 S223 同样可以实现本发明的技术方案,步骤 S223 和 224 组成第一模式动作。
这里,步骤 S224 为核心步骤,具体可分解为图 7 中的方法流程,包括:
S2241 、比较室内温度和室外温度的高低;
S2242 、若室内温度高于室外温度,则执行 S2243 ,否则执行 S2244 ;
S2243 、进入新风模式;
S2244 、进入制冷模式。
上述步骤 S2242
中的执行条件限定于室内温度高于室外温度,则进入新风模式,否则进入制冷模式,除此,也可以将执行条件放宽至一定的范围,即判定室内温度与室外温度的温度差是否超出预设的范围,若是,则进入制冷模式,否则进入新风模式。采用此执行条件判断控制进入新风模式或制冷模式的技术方案,同样落入本发明的保护范围。
上述步骤 S2243 具体为通入新风,由于 T1<T2 , T3<T2
,因此,通过比室内温度低的室外新风,有利于将 T2 调节为目标室内温度,充分利用了室外低温的能源,达到节能效果。
上述步骤 S2244
具体为利用空调设备中的制冷组件对空气进行降温,所述制冷组件包括依次连接的压缩机、冷凝器、毛细管(或电子膨胀阀)和蒸发器,制冷剂在压缩机、冷凝器、毛细管(或电子膨胀阀)和蒸发器形成的循环制冷回路中流转,所述蒸发器设置在空气换热管路处,制冷剂与空气换热管路中的空气换热将空气制冷降温,由于
T1<T2<T3 ,因此,室外新风无法帮助室内降低温度,在这种情况下,需要依靠空调设备的制冷组件将 T2 调节为目标室内温度。
以上为新风模式和制冷模式二者选一的方法流程,即在新风模式下,首先利用新风对室内温度作降温,然后等待返回到步骤 S1
进行温度获取,进入下一轮的控制,而在本发明的另一个实施例中,提供了一种进入新风模式后的扩展方法,参见图 11 ,流程包括:
S2243 、进入新风模式;
S2245 、判断室内目标温度是否低于室外温度,若是,则执行 S2246 ;
S2246
、同时进入制冷模式,具体为,一方面,通过室外低温新风空气,另一方面,驱动空调的制冷组件工作。
这种控制方法可以在节能控温的同时,可快速使室内温度达到目标温度。
参见图 1 可知,步骤 S2245 中,若判断结果为否,则等待返回步骤 S1
进入下一轮的控制,具体参见图 9 所示。
在本发明的一个实施例中,提供了第三种温度比较结果下的控制方法,参见图 8 ,包括以下流程:
S231
、温度比较结果为第三比较结果,所述温度比较结果还包括第三比较结果,所述第三比较结果为室内目标温度等于室内温度;
S232 、识别当前模式是否为第一模式或第二模式,若否,则执行 S233 ;
S233 、判定室内温度变化趋势;
S234 、判断温度下降或上升,若下降,则执行 S235 ,若上升,则执行 S237 ;
S235 、标记当前模式为第二模式;
S236 、根据室内温度和室外温度的比较结果,控制进入新风模式或制热模式;
S237 、标记当前模式为第一模式;
S238 、根据室内温度和室外温度的比较结果,控制进入新风模式或制热冷模式。
如上所述,步骤 S235 及 S236 组成第二模式动作,两者之间不限定先后执行顺序,步骤 S237
及 S238 同理。
具体地,所述步骤 S236 和 S238 的执行细节分别参见上述步骤 S214 和 S224
的方法流程。
本实施例中,判定室内温度变化趋势的规则策略包括但不限定于:在设定的时间间隔内检测室内温度,所述时间间隔不限定具体的数值,可由用户自行设置,若最近一次检测的温度结果与初始的室内温度的差值超过设定的温度阈值,则判定为有变化趋势。
步骤 S234
中,还包括以下情况:设定一个观察时间阈值,若在此观察时间阈值内,室内温度没有变化趋势,则返回 S1
进入下一轮控制,在下一轮控制中,即使上述判定结果为室内温度没有变化趋势,但极有可能与初始室内温度存在差值(只是没有超过温度阈值),导致室内温度和室内目标温度不相等。
下面,对照图 1 列举具体实例:在夏天,设定室内目标温度 T1 为 25 ℃,获取室内温度为 29
℃,室外温度为 32 °,刚开启空调而并未调节制冷模式或制热模式的情况下,由于 T1<T2 , T2<T3
,因此,直接进入制冷模式,并标记当前模式状态为第一模式,并等待进入下一轮控制过程,直至 T1=T2 ,此时判定当前模式为第一模式,则直接等待返回 S1
进行下一轮控制过程,直至 T1>T2
,由于当前正处于第一模式,因此,关闭制冷模块,并等待进入下一轮控制。在夏天开启新风模式的情况如下:夏日夜晚来临,室内温度依然很高( 28
℃),而室外温度已降至 26 ℃(高于室内目标温度 25 ℃),在此情况下,同时进入新风模式和制冷模式;甚至室外温度骤降至 24 ℃(低于室内目标温度 25
℃),在此情况下,无需开启制冷模式,只需进入新风模式即可完成将室内温度降低至室内目标温度,直至室内温度降低到低于室内目标温度,则关闭新风模块。
又比如:冬末春初的上午,室外温度大于室内温度,设定 T1 为 22 ℃,获取室内温度为 15
℃,室外温度为 20 ℃,则同时启动新风模式和制热模式;若在下午,室外温度达到 23
℃,在此情况下,无需开启制热模式,只需进入新风模式即可完成将室内温度提升至室内目标温度,直至室内温度高于室内目标温度,则关闭新风模块。现有技术中的空调,在严寒的冬季需要从冰点制热到温暖舒适的温度,是很困难的,需要大匹数的空调,并且耗费大量的电能,在晴朗天气下,冬季室外的温度大于室内的温度,利用本发明中的控制方法,即可充分利用室外新风对室内提升温度的同时,对室内空气或者进入室内的新风进行加热,节约能源,减少废气排放,符合可持续发展的理念。
在本发明是一个实施例中,提供了一种空调设备控制装置,参见图 12 ,所述装置包括以下模块:
温度获取模块,用于获取室内目标温度、室内温度和室外温度;
温度比较模块,用于比较室内温度和室内目标温度的高低,得到温度比较结果;
模式识别模块,用于识别当前模式,得到识别结果;
标记模块,用于根据温度比较结果和识别结果,对当前模式进行更新标记;
模式控制模块,用于进一步根据室内温度和室外温度的比较结果,控制进入新风模式、制热模式或制冷模式。
进一步地,所述温度比较结果包括第一比较结果和第二比较结果,所述进一步根据室内温度和室外温度的比较结果,控制进入新风模式、制热模式或制冷模式包括:
响应于第一比较结果,识别当前模式是否为第一模式,若否,则执行第二模式动作,所述第二模式动作包括:标记当前模式为第二模式,且判定室内温度是否低于室外温度,若是,则进入新风模式,否则进入制热模式;
响应于第二比较结果,识别当前模式是否为第二模式,若否,则执行第一模式动作,所述第一模式动作包括:标记当前状态为第一模式,且判定室内温度是否高于室外温度,若是,则进入新风模式,否则进入制冷模式。
进一步地,所述温度比较结果还包括第三比较结果,响应于第三比较结果,识别当前模式是否为第一模式或第二模式,若否,则判定室内温度变化趋势,包括:若判定结果为室内温度下降,则执行第二模式动作,若判定结果为室内温度上升,则执行第一模式动作。
需要说明的是:上述实施例提供的空调设备控制装置在进行对空调进行控制时,仅以上述各功能模块的划分进行举例说明,实际应用中,可以根据需要而将上述功能分配由不同的功能模块完成,即将空调设备控制装置的内部结构划分成不同的功能模块,以完成以上描述的全部或者部分功能。另外,本实施例提供的空调设备控制装置实施例与上述实施例提供的空调设备控制方法属于同一构思,其具体实现过程详见方法实施例,这里不再赘述。

23 以及新风进风口 24 连通。所述四通风阀 6 能够直接将室外机回风口 21 、空气换热管路 41 和室外机出风口 22 连通,室外机回风口 21
和四通风阀 6 之间形成室外机回风风道,室外机出风口 22 与空气换热管路 41 之间形成室外机出风风道。

连通,将室外的新风导入空气换热管路 41 中。即直接将室内空气弃用,直接引入室外的新风对新风进行温度调节,也是能够降低空气温度调节模块的能耗。
当室内空气温度低于或等于新风温度时,所述控制单元控制四通风阀 6 将室外机回风口 21 与空气换热管路
41 连通,所述室内空气经四通风阀 6 导入空气换热管路 41 中,同时四通风阀 6 将所述回风排风口 23 和新风进风口 24
关闭。也是为了能够充分利用室内空气中含有的冷量,降低空气温度调节模块的能耗。
在空调设备处于制热模式下,在室内机 100
内,当室内空气温度低于温度下限值时,所述控制单元控制三通风阀 9 将回风风道连通,将室内风回风口 11 和回风换热通道切断。此时,全热交换模块 15
不对室内风回风口 11 吸入的室内空气进行换热处理,直接让吸入的室内空气送入室外机 200
内进行处理。当室内空气温度高于或等于温度上限值时,所述控制单元控制三通风阀 9 将室内风回风口 11 和回风换热通道连通,将室内风回风口 11 和室内风出风口
12 直接连通的回风风道切断。此时,室内空气具有可利用的热量,经过全热交换模块 15
的回风换热通道处理,热量被回收,并传递给进风换热通道内即将送入室内的空气。这样,空气温度调节模块的能耗能够降低。
在室外机 200 内,当室内空气温度低于新风温度时,所述控制单元控制四通风阀 6 将室外机回风口 21
与回风排风口 23 连通,所述室内空气经回风排风口 23 排出,同时四通风阀 6 将所述新风进风口 24 与空气换热管路 41
连通,将室外的新风导入空气换热管路 41 中。即直接将室内空气弃用,直接引入室外的新风对新风进行温度调节,也是能够降低空气温度调节模块的能耗。
当室内空气温度高于或等于新风温度时,所述控制单元控制四通风阀 6 将室外机回风口 21 与空气换热管路
41 连通,所述室内空气经四通风阀 6 导入空气换热管路 41 中,同时四通风阀 6 将所述回风排风口 23 和新风进风口 24
关闭。也是为了能够充分利用室内空气中含有的热量,降低空气温度调节模块的能耗。
另外,所述控制单元内设定有空气状况参数达标范围。当控制单元判定室内空气状况参数在空气状况参数达标范围内,所述控制单元控制四通风阀 6 将所述回风排风口 23
和新风进风口 24 关闭,即不需要要引入新风,室内空气质量仍然可用。当控制单元判定室内空气状况参数在空气状况参数达标范围外,所述控制单元控制四通风阀 6
将室外机回风口 21 与回风排风口 23 连通,同时将所述新风进风口 24 与空气换热管路 41
连通。即室内空气质量较差,需要更换,引入新风,使房间内持续有新鲜的空气流动。
所述空气温度调节模块 4 包括制热组件和制冷组件。所述制冷组件包括依次连接的压缩机 42 、冷凝器
43 、毛细管 44 和蒸发器 45 ,制冷剂在压缩机 42 、冷凝器 43 、毛细管 44 和蒸发器 45 形成的循环制冷回路中流转,所述蒸发器 45
设置在空气换热管路 41 处,制冷剂与空气换热管路 41
中的空气换热将空气制冷降温。由于制冷组件属于常规的通过冷媒的压缩与释放原理实现的部件,此处不再详述。所述制热组件包括设置在空气换热管路 41 处的电加热器
46 ,所述电加热器 46 工作能够将空气换热管路 41 内的空气加热升温。电加热器 46 的使用,提高了制热的效果。制热时由于压缩机 42
管路不工作,冷凝器 43 不结霜,这样,电加热的耗能要比压缩机 42 的制热耗能降低 10%-30%,
即相比通过冷媒的压缩与释放原理实现制热的能耗低。
所述空气换热管路 41 外周包围设置有能够隔绝空气换热管路 41 内流通的空气与外界换热的保温装置
18 。使得送入室内机 100 内的空气温度保持在室内空气目标温度附近,防止热量 / 冷量的浪费。
本发明中室内机 100 和室外机 200
之间相互连接的管道不需要铜管,仅需普通的管道即可,降低了空调设备的生产成本。空气温度的调节在室外机 200 和室内机 100
内完成,制冷后的空气无需与室内的空气混合才能获得需要的温度,从室内送风总成 14
送出的风的温度即为设定的室内空气目标温度,人体的体感舒适度大大提高。同时从室内机回风口 11 吸走的空气量与室内送风总成 14
送回的空气量是等量交换,保持了房间内气压的温度,有效防止负压的产生,房间内的使用者的舒适度能够得到保证。
控制单元根据回风温度传感器和出风温度传感器的空气温度反馈控制空气温度调节模块对经回风风机吸入室外机内的室内空气进行温度调节,保证了送风总成送出的风的温度达到室内空气目标温度,室内空气温度的调节在空调设备内部完成,无需将制冷的空气从空调设备的出风口处送出在房间内与房间内的空气混合换热。本发明所述的空调设备从送风风总成送出的风即为舒适的风,使用者的体感舒适度大大提高。
以上所述仅为本发明的优选实施例,并非因此限制其专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
